I have one MO5 in a cupboard somewhere which I've never used, but a priori works. Got it from school where it was hidden in an old cupboard... it has cables to connect to a PC and everything.
It looks exactly like this: https://en.wikipedia...O5-IMG_1732.jpg
I used to go to a (different) school where the computer room was a series of MO5 networked to one old PC XT with a Hercules black & green monitor. I remember we'd squat the PC to play "advanced" games (like North and South) once we got bored of the BASIC games for the MO5. I only remember two games for it... one was a football manager kind of thing, and the other some arcade game with a helicopter exploring caverns (not "Cobra", it was not a scroller).
